I hear that heating and sudden cooling works, but I'm not a metal worker. Any help? What would a simple forge be consisted of? I'm talking about one that uses only what someone from the 1800s would have usedf (non-electric). I've researched this on the 'Net, but can't find a good answer for a very green novice wannabe forger. Know of any very descriptive links (please post link)?
